MicroPHY®采用32引脚、5mm x 5mm QFN封装，是尺寸zui小的高速以太网PHY，能够向系统媒体控制器提供一个完备的802.3媒体无关接口(MII)。

78Q2123/2133 MicroPHY可满足日益增长的新型网络的需求，例如：游戏控制台、机顶盒、数字TV等。微小的器件尺寸为电路板空间要求苛刻的应用提供了便利，器件采用3.3V单电源供电，无需1.8V稳压器或其它电压转换器。

集成HP支持自动MDI/MDI-X功能(消费类电子产品的必备功能)，可自动补偿电缆交叉连接问题，无需考虑用户介入传统设计中的线缆调整。

MicroPHY的全功能MII能够使器件非常容易地与任何802.3兼容MAC连接。MicroPHY为嵌入式应用提供了所有基础引脚，包括：复位引脚、关断引脚、可编程LED等其它引脚。片上稳压器有助于隔离不同模块之间的电源噪声，节省片外电源滤波元件。接收器的半位结构和数字时钟恢复单元大大提高了电路噪声抑制能力。

MicroPHY集成了ENDEC、扰码器/解扰码器、双速时钟恢复电路以及全功能自动协商功能。发送器包括片上脉冲整形器和低功耗线路驱动器。接收器具有自适应均衡和基线恢复电路，可qingque恢复时钟和数据。收发器可通过1:1隔离变压器与5类非屏蔽双绞线(Cat-5 UTP)连接，无需外部滤波电路。
